It appears FreeBSD implemented Linux's timerfd feature. And it appears Rust libc crate has some of the bindings, and I've now submitted rust-lang/libc#3506 to add the rest. I've also started bytecodealliance/rustix#978 to add the rustix support.

Hello.

Is there any support for MacOS? I'm facing similar issue when building on MacOS M1 (details in jimy-byerley/etherage#26)

macOS does not appear to support timerfd APIs, so there's nothing the timerfd create here can do for it.

@sunfishcode good to know this. Thanks!
